Get yourself a small tank like 5 gallons or smaller and fill it up with about 5 inches of water. Put some plants in there and heat the water to around oh I think around 80, but it has been a while since I have bred them. Might want to look the temp. up for sure online. Do not put a filter on it unless you put a small sponge filter on it. You want to keep the water surface very still so the male can build a nest. Make sure you feed them both real good for a while and then after the male makes the nest put the female in. Like I said make sure there are a lot of plants just in case the male goes after the female she will have some protection. If they do not spawn, take the female out and set her in a jar or some other container right beside the male. He should see her and he should make a nest and get interested. then try it again. Experiment around and see what works best. Also, if you just want to do this for fun then great go ahead. But if you want to make money you need to have more than one pair. You need many and you need a big set up if you ask me. Anyways just see what works. Hope this helps.
